Power Upgrading of Transmission Line by Combining AC DC Transmission and Analysis of UPFC

The basic concept in designing of any power lines in transmission of ac dc power with power upgrading using UPFC is proposed through a single circuit ac transmission line. In this proposal certain limitation are their due to the use of ground as return path. More ever the instantaneous value of each conductor voltage with respect to ground becomes higher than the Line Line voltage. By using UPFC that is unified power flow controller we can make it possible to handle practically all power flow control and transmission line compensation problem which provide functional flexibility in power which is not possible by the use of conventional thyristor control system. In this paper we have design UPFC to improve stability of power oscillation that are caused due to non linearity of the load. MATLAB Simulink model has been develop for this concept.
